Lecture: States of Consciousness

Introduction

  • Consciousness: Level of awareness of internal and external stimuli.
  • Arousal: Not only sexual; refers to being stimulated by something (e.g., fear, motivation).
  • Regulation: Managed by the Reticular Activating System (RAS).

The Reticular Activating System (RAS)

  • Function: Regulates transitions between different energy states and sleep.
  • Caffeine Impact: Antagonizes adenosine, disrupts RAS regulation leading to increased arousal.
  • Habituation: With frequent use, effects diminish, leading to increased consumption and potential side effects.

Levels of Awareness

  1. High-Level Consciousness
    • Deep focus and engagement (e.g., solving puzzles, studying).
    • Associated with executive function and decision-making.
  2. Low-Level Consciousness
    • Autopilot mode for routine activities (e.g., walking, chores).
    • Risk of missing important details.
  3. Altered States of Consciousness
    • Induced by drugs (e.g., cannabis, alcohol) or conditions (e.g., fatigue, trauma).
    • Includes meditation, hypnosis, and mental disorders.

Subconscious and No Awareness

  • Subconscious: Affects actions without full awareness (e.g., dreams, parallel processing).
  • No Awareness: Deep memories influencing behavior unconsciously.

Brain Waves and Sleep Stages

  • Beta Waves: High-level thinking.
  • Alpha Waves: Relaxed, awake state.
  • Hypnagogic Phase: Transition between wakefulness and sleep.
  • Sleep Stages: Progression from light sleep to deep sleep and REM.

Multitasking and Consciousness

  • Divided Consciousness: Managing different tasks simultaneously (e.g., driving and listening to music).
    • Requires tasks to use different sensory pathways.
  • Shifted Consciousness: Alternating focus between tasks using the same sensory pathway (e.g., texting while driving).
    • More dangerous due to complete focus shift.

Conclusion

  • Effective use of consciousness levels can enhance productivity and safety.
  • Understanding the limitations of multitasking can prevent accidents and improve task performance.
